Design a Twitter background

We are a new e-commerce business, and will be launching at the end of January. The idea behind our business is to create a wine club which is fun, engaging, simplified, and more accessible to people (particularly younger people in the range of 25 - 40). A key part of our strategy is to harness social media as an advertising and communication tool, so it is vital that our brand is well presented and conveys our values and ethos. We want to move away from the impersonal image which conventional (and frankly dull!) image of normal wine retailers and create a brand which is quirky, creative and different. We also believe that a bit of 'personal touch' is important - some examples of existing companies which I believe do this well are the craft beer clubs, Honest Brew and Flavory (among others.) We also like the ethos and approach of companies such as Brew Dog' and Innocent Smoothies. At this stage, the project is to design a Twitter banner, but if we are happy with the outcome there will almost certainly be further opportunities to work together on additional design. Our website is currently live at www.tipsywines.co.uk. I have attached our logo which has already been developed for us. In summary, we are looking for creative and different, as opposed to conventional and predictable. We want to stand out from the crowd.
